Answer:
2/3 of an hour
Step-by-step explanation:
Since Ivan has 4 total hours of music on his mp3, you can multiply the number of hours by the fraction of time:
[tex]4*\frac{1}{6}=\frac{4}{1}*\frac{1}{6}=\frac{4}{6}=\frac{2}{3}[/tex]
Given that Jazz makes up 1/6 of the total, than only 2/3 of an hour on Ivan's mp3 player would be Jazz.
